Premiers on a train

 Lenin, Stalin, Khrushchev, and Brezhnev are all riding in a train when suddenly, it stops. The conductor tells them that the rails up ahead are damaged and they need to wait.

Lenin says, "Comrades, let us call the workers nearby to help us fix the rails!"

Stalin sticks his head out the window and yells, "If this train doesn't start moving in 10 minutes, I'll have the entire crew shot!"

Khrushchev asks, "Why don't we just pull up the rails behind us and put them down in front?"

Brezhnev says, "Calm down, comrades. If we draw the curtains and rock the car back and forth, it's just like we're still moving!"

Variants typically add actions by later leaders: Gorbachev could be leading a protest on the tracks, tearing up the rails, saying the train's going the wrong way, or disembarking. Yeltsin could be derailing the train or selling it off. Putin could be climbing back on board.
